"I ran your IQFeed DDE vs. my broker vs. a level II window for some slow-moving options. I would see the level II quote change, then your feed update instantaneously. My broker's DDE, however, would take as much as 30 seconds to update. I am not chasing milliseconds, but half a minute is unacceptable." - Comment from Rob"I just wanted to tell you what a fine job you have been doing. While *******, from what I hear, has been down and out, off and on, IQ feed has held like a champ this week." - Comment from Shirin"I started a trial a few weeks back before the market went wild. DTN.IQ didn’t miss anything and beat my other provider. I decided to stay with you because of the great service through all the volatility." - Comment from Mike"IQ feed is brilliant. The support is mind-bending. What service!" - Comment from Public Forum Post"I noticed that ******* quotes locked up shortly after the interest rate announcement yesterday while yours stayed stable." - Comment from Ron in Utah"I've been using IQFeed 4 in a multi-threaded situation for the last week or two on 2600 symbols or so with 100 simultaneous daily charts, and I have had 100% responsiveness." - Comment from Scott"Thanks for following up with me. You guys do a great job in tech support." - Comment from Phelps"I have been using IQFeed now for a few years in MultiCharts and I have zero complaints. Very, very rare to have any data hiccups or anything at all go wrong." - Comment from Public Forum"I'm satisfied with IQFeed. It's the most reliable and fastest quote feed I have ever used. Although I'm a resident in China, it's still very fast!" - Comment from Xiaofei"After all the anxiety I had with my previous data provider it is a relief not to have to worry about data speed and integrity." - Comment from Eamonn

It would be really great if you could provide a function in your software to export historical data to ascii or excel. At the moment it seems this is only possible with 3rd party software (which have limited functionality) in this aspect.

We currently provide the ability to export historical data into a CSV files (1) symbol at a time in our DTNiQ software. We also offer an API that can be utilized to write your own custom application with the desired functionality.

We may also suggest products like QCollector which many of our customers find to be quite feature rich for exporting our data.

It isn't out of the question that we will provide the requested functionality in the IQ Feed Core product in the future, however it isn't on our near term roadmap.
